Twist yarn: twist textile fibers into yarn by mechanical rotation.
●Natural staple fibers such as cotton and hemp need to be twisted in order to spin into yarn.
●The physical properties and functionality of the yarn are enhanced by twisting.
●The single-ply yarn feels soft but the yarn strength is weak. In order to improve the yarn strength, two single-ply yarns are spun and twisted into double-ply yarn. The cored spandex yarn makes the yarn elastic, and the blending of natural fiber and chemical fiber improves the functionality of the yarn.
●Different yarn materials have different critical twist. The twist shall not exceed a certain value, otherwise its strength will be reduced, resulting in yarn breakage or knotting.
0-1000T/M weak twist
1000-1800T/M medium twist
Over 1800T/M strong twist
The unit (T) yarn rotates 360 degrees around its axis, which is a twist

‼️ be careful
If the yarn twist is not uniform, the fabric is prone to weft skew.
